Hi all, just would like to ask some help as to how I would go about modifying this code I created to do the following:

1 - need user input (in password field) to be echoed back as *******.
2 - need the class to open a new class (lets call that class class2 for now) upon entry of correct credentials.Many thanks!

I am guessing that you want to create another windows forum at this point.

so you may want to do something like this

if(txtUser.Text == "MJ12" && txtPass.Text == "Roswell1947")
{
	// Create instance of the mainForm class
	Form nextForm = new MainForm();
}

You would have to create a new form and in the case name it MainForm, this will then load the next form when they enter the correct sername and password.

Anyhow good luck and I hope this helps you.

Many thanks for your reply, it is helpful but the issue is that I have already have anothr class that displays a form (class2) which I want to be opened when a correct username/password is entered. Any ideas on that would be helpful. Thanks

if(txtUser.Text == "MJ12" && txtPass.Text == "Roswell1947")
{
	// Create instance of the mainForm class
	Form nextForm = new Class2();
	// We may need to make it visable
	nextForm.Visible=true;
}

I think that should work, But don't have Windows.Forms on this computer to play around with, so am abit uncertain

lol thanks for your help again, unfortunately I had tried that befre posting and I get a compilation error "the type or namespace 'class2' could not be found. (are you missing a using directive or assembly reference?)(CS0246).
Any thoughts on that ? thanks again for your help

If your second class has been defined as class2 and is accessible within your current form ( in the same project and within the same namespace ) it should work. That error suggests that it is unable to find the class named class2,

Just make certain that where this one says

public class UserLogin : Form

your second form says

public class Class2 : Form

note it is caps sensitive and I did say to use Class2 so if you have named your class 'class2' insted of 'Class2' you will have to write

if(txtUser.Text == "MJ12" && txtPass.Text == "Roswell1947")
{
	// Create instance of the mainForm class
	Form nextForm = new class2();
	// We may need to make it visable
	nextForm.Visible=true;
}

thanks pal, would you believe it I made a caps error on class declaration! i.e. it was class2 not Class2! THanks a million! that really is an annoying little error I spent ages trying to figure that out! working good now

I'm working on the same thing only i want to make my login thing to work through a data base.... Mind helping me?

with regards to echoing back input parameters in a pssword box as ***** use this:
this.textboxname.UseSystemPasswordChar = true;
